Heretics by G.K. Chesterton

To say that a man is an idealist is merely to say that he is a man; but, nevertheless, it might be possible to effect some valid distinction between one kind of idealist and another. One possible distinction, for instance, could be effected by saying that humanity is divided into conscious idealists and unconscious idealists. In a similar way, humanity is divided into conscious ritualists and unconscious ritualists. The curious thing is, in that example as in others, that it is the conscious ritualism which is comparatively simple, the unconscious ritual which is really heavy and complicated.

The ritual which is comparatively rude and straightforward is the ritual which people call "ritualistic." It consists of plain things like bread and wine and fire, and men falling on their faces. But the ritual which is really complex, and many coloured, and elaborate, and needlessly formal, is the ritual which people enact without knowing it.
